Description

Uppfinnare: M Levecque och M Mabru Prioritet begard fr (in den 15 februari 1958 (Frankrike) Foreliggande uppfinning hanfor sig till en anordning for framsthllning av fibrer av ett material, sem blir viskost i varme, sarskilt glas. Anordningen at av det slag, som omfattar ett centrifugorgan, som formar materialet till fibrer genera slungning, och ett fordelarorgan omobivet av centrifugorganet for att jamnt fordela det smalta materialet over centrifugorganets insida. Inventors: M Levecque and M Mabru Priority for (in February 15, 1958 (France) The present invention relates to a device for producing fibers of a material which becomes viscous in hot, special glass. comprises a centrifugal means which forms the material into fibers by throwing, and a distributor means unobstructed by the centrifuge means for evenly distributing the narrow material over the inside of the centrifuge means.

Det är kant att tillverka fibrer av exempelvis glas genom att inmata trait glas i ett snabbt roterande centrifugorgan, som i sin periferivagg bar ett flertal hal, genom vilka glaset slungas ut som tradar eller fibrer. En anordning for en ,dylik tillverkning är emellertid kfinslig pA grund av att det smalta, heta glaset liar en viss korroderande verkan pa materialet i centrifugorganet, vilket hi. a. kan leda till att diametern pa utslungningshalen akar. Derma nackdel blir sarskilt markbar, em man vill ha en exceptionellt hog temperatur pA det smalta glaset. It is edge to make fibers of, for example, glass by feeding trait glass into a rapidly rotating centrifuge member, which in its peripheral cradle carried a plurality of slides, through which the glass is thrown out as threads or fibers. However, a device for such a manufacture is sensitive due to the fact that the narrow, hot glass suffers from a certain corrosive effect on the material in the centrifugal means, which hi. a. can lead to the diameter of the ejection tail increasing. This disadvantage is especially noticeable if you want an exceptionally high temperature on the narrow glass.

Det har enligt uppfinningen befunnits, att namnda nackdelar kunna un:dvikas,, am centrifugorganet lake har hal fOr det smalta glasets utslungning, utan, i stallet bestar av flera axiellt efter varandra belagna, i huvudsak plana plattor, som rotera omkring samma axel. It has been found according to the invention that the said disadvantages can be avoided, in that the centrifuge means lake is slippery for the ejection of the narrow glass, but, instead, consists of several axially successively coated, substantially flat plates, which rotate about the same axis.

Med anordningen enligt uppfinningen blir det mojligt att anvanda myeket hett smalt material. Materialet, sasam glas, kan ,salunda varmas till varje onskad temperatur utan risk fOr forstOring av centrifugorganet. Det har aven visat sig, att man ,med anordningen enligt uppfinningen loan undvika olagenheter pa grund av avglasning. Om en avglasning börjar i centrifugorganet enligt uppfinningen, blir det mojligt att med centrifugalkraften avlagsna kristallerna, da. de ha uppnatt en viss storlek. With the device according to the invention it becomes possible to use very hot narrow material. The material, such as glass, can thus be heated to any desired temperature without risk of enlarging the centrifuge member. It has also been found that the device according to the invention avoids irregularities due to glazing. If a glazing begins in the centrifugal means according to the invention, it becomes possible to deposit the crystals with the centrifugal force, da. they have reached a certain size.

Plattorna ha lampligen formen av cirkelringar, i vilkas centrum fordelarorganet Ar belaget. Plattorna kunna ha olika diameter., exempelvis successivt okande eller I vista fall samma diameter. Plattorna kunna vara slata tangs kanten, men det ar iAmpligt, att de vid periferien aro forsedda med rarmor, vagor eller ojamnheter, &Isom spetsar, tom underldtta utslungningen av det smalta materialet i form av fibrer. The plates are suitably in the form of circular rings, in the center of which the distributor member is coated. The plates can have different diameters, for example successively increasing or in some cases the same diameter. The plates may be the smooth edge of the pliers, but it is appropriate that at the periphery they be provided with grooves, scales or irregularities, & Asom tips, even facilitating the ejection of the narrow material in the form of fibers.

Fordelarorganet har lampligen formen av en rotationskro,pp, som vid sin periferi har hal och som Ar anordnad att rotera tillsammans med plattorna. Fran denna rotationskropp slun.gas det smalta materialet ut under inverkan av centrifugalkraften genom Hien och fordelas salunda pa plattorna. Haden i fordelarorganet aro fOrdelade sh. ph. de olika plattorna, att man erhaller en jamn fordelning pa dessa. Goda resultat ha erhallits. ,med flera racier hal, torn aro anordnade forstallda i forhallande till varandra, och som aro anordnade sa att tva. rader hal aro belagna mellan tva narliggande plattor. The distributor member suitably has the shape of a rotating hook, pp, which at its periphery has a slippery surface and which is arranged to rotate together with the plates. From this rotating body the molten material is ejected under the influence of the centrifugal force through the membrane and is thus distributed on the plates. The head in the distributor body aro fOddelade sh. ph. the different plates, that an even distribution is obtained on these. Good results have been obtained. , with several racier hal, towers aro arranged forstallda in relation to each other, and as aro arranged said to two. rows hal aro coated between two adjacent tiles.

Uppfinningen hammer i det foljande att fkklaras under hanvisning till bifogade ritning. Fig. 1 Ar ett axialsnitt av en utforingsform. Fig, in och lb utgora detaljsnitt i stOrre .skala och visa modifikationer av anordningen enligt fig. 1. Fig. 2, 3 oak 4 utgora planvyer av olika plattor. Fig. 5, 6 och 7 aro sidovyer av kantdelarna pa plattorna enligt olika .utforingsformer. The invention will be explained below with reference to the accompanying drawing. Fig. 1 Is an axial section of an embodiment. Figs. 1 and 1b are detailed sections on a larger scale and show modifications of the device according to Fig. 1. Figs. 2, 3 and 4 are plan views of different plates. Figs. 5, 6 and 7 are side views of the edge parts of the plates according to different embodiments.

Den utforingsform, sum visas i fig. 1, omfattar tre over varandra placerade, koaxiella platter 1, sum ha formen av cirkelringar. Plattorna are fast forbundna med ett fOrdelarorgan 2, som Ar anordnat i cirkelringarnas centrala hadrum. FOrdelarorganet har formen av en cylindrisk behallare, sem dr oppen up,ptill och i sin sidovagg har hal 3. Plattorna oak 2— — fOrdelarorganet bilda centrifugorganet, som är fast forbundet ,med en roterbar axel 4. Ma-, terialet 5, sasom smalt glas, rinner ned i fordelarorganet, pa vars insida det bildar ett tunt skikt, som matar Mien 3, genom vilka glaset slungas ut pa plattorna. The embodiment shown in Fig. 1 comprises three superimposed coaxial plates 1, which have the shape of circular rings. The plates are fixedly connected to a distributor member 2, which is arranged in the central cavity of the circular rings. The distributor means is in the form of a cylindrical container which opens upwards, at the top and in its side cradle has a slide 3. The plates also form the centrifuge means, which are fixedly connected to a rotatable shaft 4. The material 5, as narrow glass, flows down into the distributor means, on the inside of which it forms a thin layer, which feeds the Mien 3, through which the glass is thrown out onto the plates.

Sasom framgar av ritningen är det lampligt att anordna tva raider hal 3 for varje mellanrum mellan plattorna. Sksom visas i fig. labar halms langdaxel befinna sig i niva med ytan, pa den mot halen svarande plattan. Darigeliom tvinga.s det smalta materialet att komma i kontakt med innerkanterna av de cirkelringformade plattorna, och flyter sedan utat pa plattornas ytor, tills det nar plattornas kanter, frail vilka det slungas ut i form av fibrer. As can be seen from the drawing, it is appropriate to arrange two raider halls 3 for each space between the plates. As shown in Fig., The longitudinal axis of the straw labs is level with the surface of the plate corresponding to the tail. Thereby the narrow material is forced to come into contact with the inner edges of the circular annular plates, and then floats outwards on the surfaces of the plates, until it reaches the edges of the plates, from which it is thrown out in the form of fibers.

Man tan aven, ,sasoin visas i fig. 1by forse plattorna; med ringformiga rannor 6, i vilka fordelarorganets hal mynna, varvid det .smalta materialet strommar genom dessa rannor och ut pa plattornas ytor. Man tan aven,, sasoin is shown in Fig. 1by forse the plates; with annular grooves 6, in which the halter of the distributor means opens, the molten material flowing through these grooves and out onto the surfaces of the plates.

Man kan eventu.ellt, se fig. 1b anordna skivor 23 anellan plattorna 1 for att underlatta styrningen ,av det material, som avgar genom fordelarorganets hal 3. It is possible, as shown in Fig. 1b, to arrange discs 23 in front of the plates 1 in order to facilitate the control of the material which is emitted through the hall 3 of the distributor means.

Dessa rannor eller -Under underlatta fiberbildningen genom att det smalta materialet lattast flyter ut vid rannornas eller tandernas utskjutande spetsar. The plates 1 are at the periphery suitably provided with radial grooves, grooves or channels 7, see Fig. 2, or teeth 9, see Fig. 4. These grooves or grooves facilitate the fiber formation by the narrow material flowing out most easily when the grooves or teeth protrude. lace.

Utforingsformen enligt fig. 1 dr vidare fOrsedd med en ringformig brannkammare 10, som ar koaxiell med centrifugorganet och som har en ringformig slits 11, genom vilken forbrdnningsgasen biases mot de utslungade fibrerna °eh drar ut dessa ytterligare, pa kant salt. For upphettning av centrifugorganet dro i den, ihaliga rotationsaxeln anordnade brannare 12 saint en konisk vagg 13, ,somistyr den av dessa brannare .alstrade hetgasen mot centrifugorganet. The embodiment according to Fig. 1 is further provided with an annular fire chamber 10, which is coaxial with the centrifugal means and which has an annular slot 11, through which the combustion gas is biased against the ejected fibers and pulls them out further, on the edge of salt. To heat the centrifuge means, the burner 12 arranged in the hollow axis of rotation draws a conical rock 13, which directs the hot gas generated by these burners towards the centrifuge means.

Plattorna 1 kmma alla vara utfOrda med sainma diameter eller ha olika diameter, varvid diametern lampligen 51:sar fran den oversta plattan till den nedersta. I detta fall kan deras periferiska kant la vara snedskuren, se fig. 5 och 6, eller skuren ratvinkligt, se fig. 7. The plates 1 may all be made with the same diameter or have different diameters, the diameter apparently 51 being from the top plate to the bottom. In this case, their peripheral edge 1a may be obliquely cut, see Figs. 5 and 6, or cut at right angles, see Fig. 7.
